I've done the best I can to find anything on the OKAY Safety Razor out of Fremont Ohio. Can any of you help me out? It was in a small box of other razors my father-in-law had purchased over the years.
Oh, I thought this was a question about Google. Like if Google doesn't know THE UNIVERSE WILL IMPLODE! Seriously, though, your razor might've come from Crescent Manufacturing, in Fremont, Ohio, east of Toledo. Check their site, maybe they can ID it if you call or email:
Wait's compendium has an Okay razor in a blue box, but it features Okay written top to bottom in a triangle pointed down. It does look similar to yours.
It says: Mfr. unidentified. Probably Unsinger Razor Blade Co. Similar or identical to a Curbo or Adelene.
